The purpose of this study was to study what effect providing the patient with preparatory concrete information had on the state anxiety depending on coping styles of patients undergoing cardiac catheterization. State Anxiety scores for 32 patients who had cardiac catheterization were examined after information was provided about the test using an audio tape. The state anxiety of patients who had a high trait anxiety level was compared to that of those who had a low trait anxiety level. The state anxiety of those who had a monitor type were compared to those of patients who had blunter type. The Trait and State Anxiety Scale of Spielberger, Miller's Behavioral Style Scale, and Krantz's Health Opinion Survey and Visual Analog Scale (Ⅰ, Ⅱ) were used. Findings were as follows : 1. Among the demographic characteristics, gender difference of the patients was significantly different for the trait anxiety level. Female patients had higher trait anxiety level than male patients. 2. Analysis of state anxiety scores indicated that the mean score of the state anxiety prior to the test was higher than the mean score of the state anxiety examined after the test. The difference was statistically significant. 3. Among the patients, 14 patients (43. 7%) used monitor type, while 18 patients (56. 3%) used blunter type. The means of preference for information measured on the Krantz' subscale was 2. 45. 4. The study results indicate that the state anxiety level of those who had a low trait anxiety level was lower than that of those who had a high trait anxiety level. 5. State anxiety levels depending upon the kind of coping style which patients used during the test were not significantly different. This study did not identify the influence of preparatory concrete information on the state anxiety depending on coping styles, and there fore a quasi-experimental study using a large sample according to different types of information, and the amount of information, coping styles is recommended.

Objective: Previous studies suggested the potential influence of YouTube videos regarding dentistry on the mass population. However, there was not any clear investigation for Korean population. We aimed to systemically analyze the type of the dentistry-related videos uploaded on YouTube Korea and the accounts used for uploading, and to assess their effect on the view count of the content. Methods: Classification, type of the accounts, and view count of the videos listed by the keyword 'dentistry' were analyzed, which were uploaded on YouTube Korea platform from September 2017 to April 2019. Kruskal-Wallis test with post hoc analysis was used to assess the effect of the classification of the videos and the type of accounts on the view count. Results: 1.026 videos were enrolled to the analysis. Primary classification of the videos was information/education, advertisement, life, news, child contents, autonomous sensory meridian response, broadcast, cartoon/game, humor, and music. Secondary classification of the videos was dental experience, advertisement, role-playing, information/education., humor, cartoon/game, child contents, life, and broadcast. Type of the accounts was dentistry associates, general public, media company, and government office (sorted by frequency). Subject of the most videos (93.6%) was general public. There was statistically significance in the view count of the videos according to the primary and secondary classifications, the account used for uploading, and target subject of the videos. Conclusion: Dentists and their associates should recognize the importance of YouTube platform and try to monitor and intervene the dentistry-related contents, considering its huge impact on the general public.

Among various tools for pop music composition, what is most frequently used by K-Pop composers is the digital sequencer program, or DAW software (Digital Audio Workstation). When it comes to making commercial music such as K-Pop, the proportion of using these programs is extremely high. By using those software, composers come to undergo an entirely different art creation process. User interface (UI) of the DAW software has a profound effect on the process of making music, particularly vis-a-vis usability and visibility. This study is an attempt to analyze the Avid Pro Tool's UI with a focus on its inherent characteristics revealed in relation with the real effect throughout music composition. This study categorizes the UI elements in the Edit Window of the Pro Tools as Grid, Track, Slip, Clip, and Fade. Those categorized elements would be analyzed through Douglas Morgan's Creative-Process theory, thereby clarifying how visual interface of the DAW software functions in music composition practically.

In modern recently technology, 3D-Audio is used to enhance immersion in Virtual Reality. This includes interest of people about VR and AR, which related to the field of computer graphics. In fact, a lot of research has been carried out in recent years into a 3D sound field. However, the existing 3D generator device used for virtual reality does not contain Doppler effect occurred by the sound comes to or leave from a listener, while an angle from the listener and the altitude of the source sound are applied. Therefore, this paper present 3D real sound utilizing Doppler effect with spatial-rotation-speaker. We map the source sound in 3D-space into a real space where a user stays and present 3D real sound by manipulating with rotation angle, phase difference, sound output volume of the sound in 3D-space, according to the location of a virtual source sound. Utilizing both natural Doppler effect of rotating sound that is occurring by spatial-rotation-speaker and artificial Doppler effect generated by frequency-modulation of sound quality could improving the virtual reality for sound condition for perspective listening.

In case of an emergency such as a fire on a building and there is a need to evacuate the occupant in that building, it is important to have the guidance information effectively delivered to the evacuating occupants to guide them toward a safe direction using audio sensual media. And, it is also very important to prevent the evacuating occupants getting lost or falling astray, away from the direction toward safety. The purpose of this study, in this respect, is to examine the possible application of the precedent sound effect, with which the evacuating occupants may get a sense of the direction where the announcement comes from. With such an effect, an experiment was conducted to measure the extent to which people can hear the preceding and the following sound in terms of the acoustic pressure level changes and delay time changes, with a view to make the optimal evacuation-guidance announcement or sound. The optimal evacuation guidance sound (announcement) per each of the experimental indoors environments were as follows; 1) Regarding the optimal condition for the evacuation guidance announcement sound in the space of a lecture room, the direction of the advanced sound is positively recognized when the follow-up sound has the delaying time of 10 ms~50 ms in comparison with the advanced sound or when there is no difference between the acoustic pressures of the advanced and follow-up sounds or the acoustic pressure of the advanced sound is higher than that of the follow-up sound. 2) Regarding the optimal evacuation guidance announcement sound in the space of a hall, the advanced sound is positively recognized when the follow-up sound has the delaying time of 20 ms~60 ms in comparison with the advanced sound. 3) Regarding the optimal evacuation guidance announcement sound in the space of a gymnasium, the advanced sound is positively recognized when the follow-up sound has the delaying time of 10 ms~40 ms in comparison with the advanced sound or when the sound pressure of the advanced sound has a higher level than or the same level as that of the follow-up sound.
